Solving Quadratic Equations by completing the square
xz^2 - 3z - 5 =0
1 answer:
Answer:
x=3z+5
/z^2
Step-by-step explanation:
Let's solve for x.
xz^2−3z−5=0
Step 1: Add 5 to both sides.
xz^2−3z−5+5=0+5
xz^2−3z=5
Step 2: Add 3z to both sides.
xz^2−3z+3z=5+3z
xz^2=3z+5
Step 3: Divide both sides by z^2.
xz^2
/z^2
=
3z+5/
z^2
x=
3z+5
/z^2
Answer:
x=3z+5
/z^2
